If you can imagine it you can create it,
If you can dream it, you can become it.
(Ward, William Arthur)
I believe that life is for one time, and there is opportunity for us to self imporve it. We can make, what we believe, and if we imagine positively, constructively, and happily, then no doubt we can become it.
I want to link here another quote, which is a great lesson for me all the time:
"Say you are well,
or all is well with you,
And God shall hear your words and make them true."
(Ella Wheeler Wilcox)
